Arí van Twillert is a luxury lingerie and clothing brand based in Rotterdam, The Netherlands.


We are loved for our innovative designs and wearable creations,

we use technology to innovate function while playing with form,

storytelling is at the heart of what we do.



We are currently seeking several (design) engineering interns. We create all of our designs in our atelier based in De Wasserij, the new Rotterdam based fashion hub. The atelier is an open space, so you will see and experience the whole process. In our atelier the custom fit lingerie is created directly by Lidewij and our production team.

We perform 3D scans of our clients which will be converted in perfectly fitting bra patterns via our in-house developed algorithms. Next to that our redesign of the traditional underwire is custom for every client, 3D printed and patent pending. As a (design) engineering intern you will assist in the conversion of 3D body scans to bra patterns and 3D prints.

If you are looking for a graduation assignment, we have an interesting new project for you to work on. Please let us know if you are looking for a graduation project when you apply.







If you are interested in this opportunity, please send a copy of your CV and cover letter directly to with the subject “Engineer Intern” (if you prefer you can send your application in Dutch).
